Mammillaria tuberculata = Mammillaria tuberculata Engelm., Syn. Cact. U.S.: 12. 1856. Cactus tuberculosus (Engelm.) Kuntze, Revis. Gen. Pl. 1: 261. 1891. Notes. When comparing the original description Mammillaria tuberculata (https://www.biodiversitylibrary.org/page/32558530#page/12/mode/1up), it clearly corresponds a duplicate of the description of M. tuberculosa Engelm. Therefore, in the absence of diagnosis and designation of a type, it should be considered as nomen nudum ( Turland et al. 2018).
